necticut, have invented certain new and useful Improvements --in'A Pipe-Couplings, of which the following `is a full, clear, and exact description.

This invention relates to pipe couplings, and has special reference to means for coupling a pipe to a branch wrought from the intermediate portion of a sheet metal body or union to form a T. The invention is not limitedl in all of its aspects, however, to the connection of al pipeto a T body, as the character of the main portions of the two bodies to be connected is more or less immaterial.

The primary object of the invention is to provide a very strongand durable connection between apart such as awrought branch in a T, "and an intermediate supplemental section set'on said branch for the purpose of securing a pipe or other member thereto, the means or reinforcing the joint between the branch and the4 supplemental section having the additional function of positioning the pipe properly with respect to the T or other member.

To this and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of the T body with the nuts in place on the respective branches, Fig. 2 is a v1eW partly in elevation and partly in section, with the nuts removed. Fig. 3 is a vertical lon itudinal section of the device with two o thecouplings completed, and Fig. 4 is a detail sectional view of one of the branches of the T body.

Referring to the drawing, 5 indicates a T bod formed of sheet metal, having an intera tubular branch 6. On top of the open ranch is placed a separate su plemental section 7, as shown in Fig. 14. This section is of sleeve-like form and is provided with exterior screw threads 8 on` which a nut 9 is screwed. The -sleeve-likebody of the section 7 has-approximately the same internal diameter as the branch6. At its lower extremity it is projected laterally beyond the upper edge of the branch 6 to form at one side an internal shoulder 10, and at the opposlteor outer side it presents a bead 11. The section 7 is secured to the branch 6 by lhaving its bottom edge placed directly on the top edge of the branch 6, after which the bead 11 is clenched against the adjacent portion of the branch 6, the connection being completed by the use of solder. In this manner a very sim le and inexpensive connection is made. he shoulder 10, projecting inwardly from the section 7 at the lower edge of the latter and overhanging the top` edge of the upwardly extending branch of the T body, provides a seat for a pipe 12 set in the section 7, as shown in Fig. 3. The pipe 12 is thereby effectively supported on the shoulder or flange 10 and it 1s held in place by means of the nut 9 which compresses a gasket 13 against the outer surface of the pipe in a Well known manner. The shoulder 10, which is preferably squared off at the top and bottom, not only has the function of supporting the pipe 12 in the proper `position with respect to the T, but also of strengthening very materially the joint between the branch 6 and the sup lemental section. This arises from the that by the construction described the lower end or base of the supplemental section, where the latter rest-s on the branch 6, is materially thicker than the wall of said branch and overhangs the latter at opposite sides, as shown in Fig. 4. Hence the.. supplemental section has a firm and substantial bearingon the branch, and in case solder is used in making the connection, as described, it will be obvious that the comparatively extensive surfaces of the branch and section which are located close to or in contact with act i each other form a substantial anchor for the adhesive material.

The two ends of the T body are provided with threaded portions 14, which may be spun in the sheet metal, and on these threaded portions are fitted nuts 9 similar to that previously mentioned. In this case the pipe 15 (Fig. 2) is positioned in the mouth of 1ts shoved into the Tbody, as` will be understood. The spun bead 16 forms an especially inexpensive yet effective form of stop.

In assembling the parts, as shown in Fig. 3, the 'pipes 12 and 15 are thrust into their respective branches until the edges of said pipes abut the respective stop members. The nuts 9 engage the threads of the respective branches in order'to compress the gaskets against the respective pipe sections. The assemblage is very easy and yet the c parts are accurately positioned so that the T Aconstituted by an exterior-bead extending over the outer surface of the tubular member, and a shoulder projecting inwardly from said sectiony immediately above the mouth of said tubular member to reinforce the joint and.to seat the pipe in said section, and a nut on said fsection to secure the pipe therein; substantially as described.

2. As an article of manufacture, a sheet metal T body having a branch wrought therein and provided with an open end or mouth,in combination withla supplemental section having a base portion of greater thickness than and seated on the mouth of said branch, said base portion being. constituted by a bead\extending over` the outer surface of said branch, and by a shoulder projecting inward from the section immediatel'y'adjacent the joint between the latter and the branch and-overhanging the mouth of the branch atl the inside; substantially as described.

3. As an article of manufacture, a sheet metal T body having a branch wrought therein and provided with an open end,`in combination with 'a supplemental section having a widened base set on the open end of said branch and constituted by a bead extending over the outer surface of the branch,

and a squared oiivshoulder projecting in-` ward beyond the inner surface of said section approximately in line with said bead and affording a stop for a Ipipe inserted in said section; substantially as described.

4. As an article of manufacture, a vsheetmetal T` body having a. branch wrought therein and provided with-,an open end or mouth, in combination with a supplemental section having a base rest-ing on and of greater Width than the mouth of saidbranch, said baseL being constituted by a bead at the outside of the section extending over the outer surface of the branch, and a lshoulder projecting inward from the inner surface-of said section approximately in line with said bead, said shoulder beingsquared ofi' at the bottom to make a substantial joint with the branch, and squared off atv the top to seat a pipe in said section; substantially as described. 4

In witness whereof, I have hereunto set my hand on the 9th day of July, 1912.
